TL;DR — What Changed in IRDAI's Master Circular on Health Insurance
On 29 May 2024, the Insurance Regulatory and Development Authority of India (IRDAI) published a consolidated Master Circular on Health Insurance Business that replaces 55 older circulars and rewrites several core rules that govern every health insurance policy sold in India. Four changes affect every Indian family directly: the pre-existing disease (PED) waiting period is now capped at 36 months (down from up to 48 months), the age cap on enrollment has been removed, the free-look period is extended to 30 days, and the moratorium period after which a claim cannot be denied for non-disclosure is reduced from 8 years to 5 years. These rules apply to existing policies on renewal as well as new policies, so reviewing your current policy against the new framework is worth 30 minutes of your time.
This guide walks through each change, what it means in practice, and what you should do at your next renewal. Every claim cites the source IRDAI document so you can verify with the regulator directly.
What is the IRDAI Master Circular?
The Master Circular on Health Insurance Business (Reference No. IRDAI/HLT/CIR/MISC/77/05/2024) is a consolidated rulebook published by IRDAI that brings together rules for health insurance from 55 separate older circulars into a single document. It applies to all general and health insurance companies licensed in India and covers everything from how policies are designed, how claims are processed, how grievances are escalated, to how policyholders are protected during portability.
For policyholders, the key takeaway is that the rules in this circular are not optional. Every insurer must comply, and existing policies must align with the new rules at the next renewal. If your insurer is still applying older rules (for example, a 48-month PED wait), you can quote the Master Circular and ask for the change.
Top 9 Changes Explained
1. PED Waiting Period Now Capped at 36 Months
The single most important change for anyone with a pre-existing condition like diabetes, hypertension, asthma, or thyroid disorders. Before the circular, insurers could enforce a waiting period of up to 48 months (4 years) before pre-existing diseases were covered. The Master Circular now caps this at 36 months (3 years) across the industry.
What it means:
- If your current policy says "48-month PED waiting period", at your next renewal that drops to 36 months
- New policies sold after 1 April 2024 must follow the 36-month cap
- Disclosed PEDs disclosed at the time of buying are covered after 36 months continuous coverage
What stays the same:
- You still have to disclose all PEDs truthfully at the time of buying. Non-disclosure remains the number one reason claims get rejected
- Specific illnesses (kidney stones, hernia, cataract, etc.) may still have a separate 24-36 month waiting period — these are listed in the policy schedule
2. No More Age Cap on Buying Health Insurance
Before the circular, many insurers refused to enroll new customers above age 65. The Master Circular removes this cap. Insurers must offer health insurance to any individual irrespective of age, including senior citizens.
What it means:
- A 70 or 75-year-old can now buy a fresh health insurance policy in India for the first time
- Insurers can still apply higher premiums and stricter underwriting (medical tests, co-payment) but cannot refuse coverage on age alone
- Specialised senior citizen plans now compete with regular plans for the older age group
This is genuinely a structural shift. Indian families with parents in their 70s who previously had no insurance option now have one.
3. Free-Look Period Extended to 30 Days
The free-look period is the window during which you can cancel a newly bought policy and get a refund. Earlier this was 15 days for most policies. The Master Circular extends it to 30 days across all health insurance policies.
What it means:
- After buying a policy, you have a full month to read the policy wording and decide if it suits you
- If you cancel within 30 days, the insurer must refund your premium (minus stamp duty and pro-rated risk premium for any days covered)
- If you spot a sub-limit, co-payment, or exclusion you didn't notice during purchase, you have time to switch
4. Moratorium Period Reduced from 8 Years to 5 Years
The moratorium period is the timeline after which an insurer cannot reject a claim for non-disclosure of a pre-existing condition (except in cases of proven fraud). Previously this was 8 years of continuous renewal. The Master Circular reduces it to 5 years.
What it means:
- After 5 continuous years of policy renewal with the same insurer, the insurer cannot dispute a claim citing non-disclosure of pre-existing conditions
- This protects long-term policyholders from late-stage claim disputes
- Fraud is excluded — if the insurer can prove deliberate misrepresentation, they can still deny
5. Cashless Everywhere Mandate
In a separate but linked move (issued via the IRDAI 'Cashless Everywhere' circular dated 23 January 2024), insurers must now process cashless claims at any hospital, not just network hospitals.
What it means:
- You can walk into any hospital — not just one on your insurer's panel — and request cashless treatment
- The insurer must respond to the pre-authorisation request within 1 hour for planned procedures and 3 hours for emergencies
- The hospital settles the bill directly with the insurer; you only pay non-covered items
In practice, network hospitals still process cashless faster because their systems are pre-integrated with the insurer. Non-network hospitals may need extra documentation. NYVO's separate guide on Cashless Everywhere walks through how to use this in practice with each major insurer.
6. Faster Claim Settlement Timelines
The Master Circular tightens claim turnaround times. The key SLAs:
| Claim type | New IRDAI timeline |
|---|---|
| Cashless pre-authorisation (planned) | Decision within 1 hour |
| Cashless pre-authorisation (emergency) | Decision within 3 hours |
| Final cashless authorization at discharge | Within 3 hours of receiving discharge summary |
| Reimbursement claim decision | Within 30 days of receiving complete documents |
If an insurer breaches these timelines without a valid reason, you can escalate to the Insurance Ombudsman.
7. Portability Rules Strengthened
Portability lets you switch insurers without losing your accumulated waiting period credits. The Master Circular tightens the timelines and clarifies the rights of policyholders:
- Apply at least 45 days before renewal
- New insurer must respond with acceptance or rejection within 15 days
- Credit for waiting period already served must be granted in full for the same condition
- The new insurer cannot impose a fresh waiting period for diseases the old policy already covered
8. Standardised Definitions Across the Industry
The Master Circular standardises 50+ definitions across all health insurance policies in India — Sum Insured, Pre-existing Disease, Cashless Facility, Critical Illness, Day Care, Hospitalisation, Pre/Post Hospitalisation, and others. Earlier, every insurer had slightly different definitions that led to claim disputes.
What it means for you:
- Policy wording from any IRDAI-licensed insurer now uses the same definitions
- Comparing two plans is easier because terms mean the same thing
- Disputes over interpretation of common terms are reduced
9. Stronger Grievance Redressal Framework
Every insurer must publish a clear, multi-stage grievance process and resolve complaints within strict timelines:
- Acknowledge complaint within 3 working days
- Resolve within 15 working days
- If unresolved, the policyholder can approach the Insurance Ombudsman (handles disputes up to ₹50 lakhs) or file a consumer complaint
The Ombudsman must dispose of complaints within 90 days, and the order is binding on the insurer up to ₹30 lakhs.
What You Should Do at Your Next Renewal
Take 20 minutes at renewal to verify these against your current policy:
- Check your PED waiting period — if your policy schedule still says 48 months, ask the insurer for a written confirmation that the waiting period now reads 36 months under the Master Circular
- Verify the free-look clause — should now read 30 days, not 15
- Note your moratorium counter — you cross the protection threshold at 5 years of continuous renewal, not 8
- Confirm Cashless Everywhere is enabled — ask the insurer whether their cashless network hospital list and the Cashless Everywhere helpline cover your preferred hospitals
- Read the standardised definitions — most insurers have updated their policy wordings; verify the new wording is what was issued to you
Bottom Line
The Master Circular is the most policyholder-friendly health insurance regulation India has seen in over a decade. The 36-month PED cap alone is enough reason to revisit any policy bought before April 2024, especially for families managing diabetes, hypertension, thyroid, or cardiac conditions.

Frequently Asked Questions
Does the IRDAI Master Circular apply to my existing health insurance policy?
Yes. The rules apply to existing policies at the next renewal and to all new policies issued after 1 April 2024. Insurers must update their policy wordings to comply, even for legacy customers. If your renewal notice does not reflect the changes, contact the insurer's grievance cell quoting the Master Circular reference (IRDAI/HLT/CIR/MISC/77/05/2024).
What if my insurer still says my pre-existing disease waiting period is 48 months?
Quote the Master Circular and ask for a written response. The 36-month cap is industry-wide and is not optional. If the insurer refuses to change it, escalate to the IRDAI grievance redressal portal at igms.irdai.gov.in and, if unresolved, to the Insurance Ombudsman.
Can a 70-year-old senior citizen buy a fresh health insurance policy in India in 2026?
Yes. The Master Circular removes the maximum entry age cap, so insurers must offer cover to any individual regardless of age. Premiums for senior citizens are higher and may include co-payment and mandatory medical tests, but the insurer cannot refuse coverage on age grounds alone.
What is the new free-look period for health insurance policies?
30 days from the date of receiving the policy document. During this period you can return the policy and receive a full refund of the premium, minus stamp duty and a pro-rated risk premium for any days the policy was active.
When does the 5-year moratorium protection start?
From the date of first issue of the policy with that specific insurer. After 5 continuous years of renewal without a break, the insurer cannot reject claims citing non-disclosure of pre-existing conditions, except in cases of proven fraud.
How is "Cashless Everywhere" different from regular cashless treatment?
Earlier, cashless treatment was only available at hospitals on the insurer's empanelled network. Under Cashless Everywhere, cashless treatment must be offered at any hospital that meets the basic registration norms, even if it is not on the insurer's panel. Pre-authorisation timelines are 1 hour for planned procedures and 3 hours for emergencies.
Can my health insurance claim be rejected after 5 years of continuous renewal?
Only in cases of proven fraud. The Master Circular's 5-year moratorium protects long-term policyholders from claim rejection on grounds of non-disclosure of pre-existing conditions. The burden of proving fraud is on the insurer.
